HEATER FOR CLAPPING-TOOLS' AND SOIJDEBING IRONS.

Application filed September 4, 1915.

To all whom it may concern:

Be it known that I, WILLIAM A. WALKER, a citizen of the United States, residing at Enterprise, in the county of Clarke and State of Mississippi, have invented certain new and useful Improvementsin Heaters for Capping-Tools and Soldermg-Trons, of which the following is a specification, reference being had to the accompanying drawm 's.

This invention relates to an improved heating device for capping tools, soldering irons and like heating tools.

The present invention has for its primary object to provide means carried by the tool, whereby the head thereof may be continuously heated to a high degree, thus saving considerable time in the operation of the device.

It is another and more particular object of the invention to provide a heater for the chambered head of a capplng tool, such as is commonly employed for soldering tops upon cans, the invention embodying in-its construction, a fuel supply tank secured upon the shank or handle of the tool, a heater cylinder or burner tube projecting into the chamber of the toolhead' and having a foraminated portion and means for vaporizing the fuel supply and admitt ng the same mixed with air to theheater cylinder.

The invention has for a further general object to improve and simplify the construction of heating devices for the above purpose and to produce a highly serviceable and convenient heating means for such tools which will not add materially to their manufacturing cost.

With the above and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a vertical sectional view of a capping tool for fruit cans; Fig. 2 is a horizontal section taken on the line 22, of Fig. 1; Fig. 3 is a view similar to Fig. 1, showing theheater as applied to a soldering iron; and Fig. 4 is a section taken on the line 4-4, of Fig. 3.

Referring. more particularly to Figs. 1 and 2 of the drawing, 5 designates the capping head of a tool, which is of circular form and isprovided with an annular flange Specification of Letters Patent.

POSltiOIl to be sealed head is also Patented May 30, 1916. Serial No. 49,058.

6 upon one end whichis' designed for engagement upon the solder strip adapted to be arranged upon the outer edge of a can top or'cover when the same is placed in upon the end of the can body. This head is formed with a chamber 7 opening upon one side of the head, as clearlyshown in Fig. 1. The tool provided with a threaded openlng in which a hollow tubular handle or shank 8" is 'detachably engaged. The body wall of the tool head5 is provided with a plural ty of openings 9 therein communicating with the chamber 7.

10 designates a bracket member which is securely fixed upon the tool head over the open side of the chamber 7. This bracket member has an opening 11 formed therein, threaded at one of its ends to detachably re ceive' one end of the heater cylinder 12. The bracket 10 is also formed with a laterally projecting arm l3'having a passage 14 therein and the outer end of said arm is angularly disposed, as at 15 and formed with an exterior-1y threaded boss 16.

On this threaded boss a nut 17 is engaged to close the outer end of the passage 14. The wall of the passage 14 in the angular end of the arm, opposite to the nut 17, is provided with a threaded'opening to receive the detachable valve seat member 18 having a tapering bore to receive the point of the adjustable needle valve 19 which is threaded in the'arm 14.

Upon the upper end of the tubular handle 8, an oil reservoir 20 is detachably mounted and to thebottom thereof the fuel supply pipe 21 is connected, said pipe being secured by means of a bracing band or sleeve indicated at 21 to the handle 8 at a point intermediate of its ends. The supply pipe 21 is extended through one side of the tool head 5. and across the chamber 7 therein in parallel relation to the heater cylinder 12 and between the same and the handle 8. The extremity of this supply pipe is connected to the passage14 in the bracket member to supply the fuel thereto. This horizontally disposed end portion 22 of the fuel supply pipe becomes highly heated so that the fuel in passing therethrough is vaporized. The lower portion of the heater cylinder 12 is formed with a multiplicity of jet orifices 23, from which the flames are directwall of the tool head so that said wall and I the flange 6 thereon are highly heated during the operation of the device. 7

When it is desired to use the tool, the

. heater cylinder 12 is first initially heated by inserting a'taper into said cylinder through the opening 11' and the oil in the end portion 22 of the supply pipe is vaporized. When the needle valve 19 is opened, the

vaporized fuel which is under pressure passes through the bore of :the valve seat member and the opening 11 of the bracket into the cylinder 12 and with the vaporized oil, air is run intosaid cylinder. By msert- V ing the taper within the cylinder, the vapor may be ignited. The heater will operate continuously aslong as the supply of fuel lasts and the needle valve 19 remains open and the end wall of the tool head will, therefore, at all timesbe maintained at a very high temperature, so that when the flange 6 is applied to the strip of solder the same Willbe melted and, of course, will flow into the chamber or groove provided'for the same in'the can body in which the cover or top of the can is seated. When the tool is removed, the solder will cool and harden,

thereby permanently sealing the top of the can in place. h V

In Figs. 3 and 4: of the drawing, have shown'my improved heater as applied to the well known soldering. iron commonly employed by tinners. The iron or head 2&7

is provided with a chamber opening through opposite sides of said head. The burner proper is in the form of a tube 26 which extends longitudinally into the head at one side of the chamber 25 and has its inner end horizontally extended across the chamber, as indicated at 27 the lower portion of said end of the cylinder being foraminated. The needlevalve28 is mounted upon the end of the head 24 and controls the supply of vaporized fuel to the outer end of the burner tube 26. The head 24 is also formed upon opposite sides of the handle connection with longitudinal passages 29 which are connected by a pipe 30 extended through the chamber 25. One of the passages 29 communicates with the bore of the needle valve bracket, while to the other of said passages a fuel supply pipe extending from the reservoir carried by the tool handle is connected. The heater as applied to the soldering iron, operates in exactly the same manner as above described with reference to the capping tool. In eachof the tools the hollow handle is preferably provided with a number of openings 31 therein adjacent to the tool head in order to admit of the escape of the heated air risingthrough the tubular handle and thereby prevent the handle being highly heated throughout its length. The opposite open ends of the chamber 25 in the head of the soldering iron are e5 closed by plates 32. Each of these plates has an opening 33 therein whereby air is freely admitted to the heater chamber. By the provision of such a heating device upon the soldering iron, it is unnecessary to pro- 'vide a number of the tools to be heated in a furnace.

From the foregoing description taken'in connection with the accompanying drawing' the construction, manner of operation an several advantages of my invention will be clearly and fully understood. It will be seen that I have produced a very simple, convenient and serviceable heating device for capping tools, soldering irons and like implements, whereby the tool head may be maintained in a highly heated condition with a minimum consumption of fuel. The several parts of the device are exceedingly simple in form and may be readily removed and replaced by new parts when necessa at nominal expense. In view of the excee ingly simple construction of the invention, the same will add but little weight to the tool so that the entire apparatus may be handled with facility by the operator.

While I have shown and described the preferred construction and arrangement of the several elements of the device, it is to be understood that the same is susceptible of considerable. modification therein and I therefore reserve the privilege of resorting to all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

Having, thus described this invention, whatI desire to claim as new and secure by Letters Patent, is

1. The combination with a tool head provided with a chamber opening upon one side of the head, a bracket secured upon the tool head over the open side of the chamber and closing the same, said bracket having an opening therein, a partially foraminated heater cylinder removably mounted in said opening and extending into the chamber, a handle for the tool head, a fuel reservoir mounted on the handle, a supply pipe consecured upon the head over the open side of the chamber, said bracket having an opening therein a heater cylinder open at one end and detachably mounted in the opening of the bracket to extend into said chamber, a tubular handle connected to the tool head and provided With an outlet opening for the heated air, a fuel reservoir mounted on said handle, a supply pipe connected to the reservoir and extending through said chamber in spaced relation to the heater cylinder, said bracket being provided With a laterally extending arm having an angularly disposed end portion, and a fuel receiving passage extending longitudinally through the arm to which the supply women of thin patent may be obtained for five cents each, by addressing the pipe is connected, one side of the heater cylinder being foraminated to direct the jet flames upon the end Wall of the tool head, and a needle valve mounted in the angular end of the arm to control the supply of fuel to the open end of said cylinder.
